If you're required to wear glasses or contact lenses, it's a good idea to
a. keep an extra pair in your trunk
b. keep an extra pair in your glove box
c. avoid driving at night
d. avoid driving when it's raining

B. Keep an extra pair in your glove box.

On the off chance that your optometrist has guided you to wear glasses or contact lenses for driving, ensure you wear them, in any event, for short outings and keep an extra pair in the vehicle in the glove box.
